About 6 months ago was driving front brakes went out. Realized that the hard line in the front bent and broke. So I replaced it and they were good for about 3 months. Then happen again. So realized it might be do to the 6 inch lift on my truck and the fact that I do a lot of U turns on my way to work. Had a shop fix them and they got rid of the hard lines and put in stainless steel braided lines without the hard line, now they have broke to!! Any ideas or a store online that I can buy better lines from?
